  • Patent number: 9962926
    Abstract: The present invention relates to a method of correcting a position of a stencil mask which comprises receiving fiducial information from a screen printer, extracting position information of a pad and position information of a solder formed on a board through measuring by a solder paste inspection apparatus, estimating an x, y offset value and a rotating amount of a stencil mask based on the fiducial information by using the position information of the pad and the solder, and transmitting the x,y offset value and the rotating amount of the stencil mask to the screen printer. Thus, a reliability of solder forming process may be increased by correcting a stencil mask position by transmitting a feedback of an x,y offset value and a rotating amount of the stencil mask from a solder paste inspection apparatus, in which the x,y offset value and the rotating amount are estimated based on fiducial information transmitted from the screen printer.

    Abstract: A screen printing apparatus for printing paste on a printed pattern of a print target constituted of a substrate or a plurality of aligned substrates includes a mask having a plurality of opening patterns different in size from one another. The screen printing apparatus images the substrate or one of the aligned substrates constituting the print target, and calculates a level of deformation by expansion and contraction of the print target, based on a result of the imaging. The screen printing apparatus then selects an opening pattern from among the opening patterns, based on the calculated level of deformation by expansion and contraction of the print target, brings the print target into contact with the mask to superimpose the selected opening pattern on the printed pattern, and deposits the paste on the printed pattern.

    Abstract: A new 3D stencil mask guides deposition of a shaped structure, typically an electromagnetic device component, onto a non-planar surface. The 3D stencil mask includes islands and bridges from prior art two-dimensional lettering stencils, but raises the islands and stencils above the side of the 3D stencil mask facing a non-planar surface, forming undercuts, so that material particles, such as from vacuum metal deposition, will form connected shapes. The 3D stencil mask is also configures so that the dimensions of the resulting electromagnetic structures are altered from a simple projected image of a structure designed for a planar surface so that the electromagnetic properties of the deposited structure are more nearly the same as those of a corresponding structure on a planar surface.

  • Patent number: 8893614
    Abstract: There is described a device and method for magnetically transferring indicia to a coating composition, such as an ink or varnish, applied to at least a part of the surface of a substrate, the coating composition comprising at least one type of magnetic or magnetizable particles. The device comprises a body subjected to a magnetic field generated by appropriate electromagnetic means, which body carries determined indicia in the form of engravings on a surface of the body, which engravings influence orientation of field lines of the magnetic field. The body comprises at least one layer of material of high magnetic permeability in which the engravings are formed. In unengraved regions of the layer of material of high magnetic permeability, the field lines of the magnetic field extend substantially parallel to the surface of the body inside said layer of material of high magnetic permeability.

  • Publication number: 20140331874
    Abstract: A screen printing apparatus includes a print screen including a printed pattern through which an ink passes, a scraper that coats the ink on the print screen, a squeegee that makes contact with the print screen and pushes out the ink through the printed pattern. A control unit may control a transfer of the scraper. After the ink is coated on the print screen, a lower portion of the scraper is transferred to a direction, in which the squeegee is disposed, by the control unit and disposed on the squeegee. The apparatus helps avoid uneven distribution of that could result in undesirable “stains” on a substrate.

    Abstract: A light receiving section 27b receives a measurement beam, which is cast from a light projection section 27a and partially blocked by cream solder 19 scraped up by a squeegee 16, whereby a sensor 27 measures a one-dimensional size of a predetermined region of a cross sectional profile of the cream solder 19 as a cross sectional paste length and takes the cross sectional paste length as an index for an amount of residual cream solder 19. The amount of residual cream solder 19 can be numerically grasped at all times, so that versatility and accuracy in detecting the amount of residual cream solder 19 can be assured.

  • Publication number: 20140318396
    Abstract: A method of partially imaging a substrate, for example glass, with a print pattern comprising layers of ceramic ink in substantially exact registration. The method relies on a mask ink layer defining the print pattern and differential thermal expulsion of ceramic ink medium during a heat fusing process between the areas outside the print pattern and within the print pattern. This results in pigment and glass frit forming a durable image material adhered to the substrate within the print pattern and non-durable material outside the print pattern, enabling its removal outside the print pattern to leave the desired layers of ceramic ink within the print pattern in substantially exact registration.

  • Patent number: 8869694
    Abstract: A screen-printing panel comprising a locking strip sewn to screen-printing mesh is described. The mesh along an edge of the panel is folded around the locking strip and secured using a line of stitching. A gap between the end of the locking strip and the edge of the mesh contributes to corner softening. Another gap between the end of the stitching and the end of the locking strip also contributes to corner softening. Locking strips have various cross sections including rectangular, triangular, and complex curves. Two colors of thread may be used to aid in orienting the panel. An adhesive may be used to hold the mesh to the locking strip for convenience during handling and sewing.
